Molded fiber containers for a variety of beverages

A system for manufacturing a molded fiber beverage container, comprising:

• a fiber production apparatus, comprising one or more fluid dispensing units and one or more heating units, configured to produce a fiber sheet having a physical barrier to liquids by:
• dosing a fiber with a stearate or a saturated long chain fatty acid salt,
• dispersing undissolved stearate or undissolved saturated long chain fatty acid salt to allow for preparation of a homogenous mixture including the dosed fiber, and
• adding a divalent or trivalent metal salt to precipitate the stearate or the saturated long chain fatty acid salt from the homogenous mixture, wherein the precipitate is on a surface of the fiber and forms a physical barrier to liquids into the fiber, wherein the fiber is formed as the fiber sheet;
• a cutting apparatus, comprising one or more blades to cross-cut the fiber sheet into fiber sections;
• and
• a paper product forming apparatus, comprising at least one slitting tool, at least one pressing tool, and at least one cutting tool, configured to mold one or more portions of the fiber sections under one or more of heat, wet chemicals, or pressure to produce a plurality of finished paper-based beverage container products.
